Within the world of home additions, it's considered a midget, a pretender, a shadow of the real thing. It's called a bump out, and definitions of it vary.
Some say that the bump out is just a few feet jutting out to add space to an existing room. Others say that a bump out can be a full room itself. I tend to go with the former.
It's wrong to think that the bump out will be cheaper, on a foot-to-foot basis, than a full addition. Usually, it's more. But because you're laying down less square footage, it's cheaper. Got that?
It's a kitchen nudged out to make space for a dining room. It's bathroom opened up just a hair more for that big whirlpool tub. It's that window seat with books.
It's a bump out.
